Description
Technical field
The utility model relates to a kind of fixture, particularly relates to a kind of rivet welding equalizer bar fixture.
Background technology
Equalizer bar is one of vitals of automobile composition, generally be formed by connecting by multiple punching parts rivet welding, due to the shaping very difficult control of punching parts, produced stamping parts size may not meet drawing requirement, only each stamping parts is simply located when workman welds simultaneously, there is no special fixture, then by stamping parts one by one rivet welding connect, do so easily cause last produced equalizer bar size and standard deviation excessive.In addition, because equalizer bar is hollow structure, heating when welding can cause the expansion of material, affects final mass, thus weld last as can increase a metal charge at hollow space, when preventing welding, equalizer bar internally expands and causes distortion.But the equalizer bar inner surface after welding because of expansion extrusion packing thing, can cause filler to take out difficulty, is generally taken out by filler by the mode of beaing or prizing, take time and effort.
Utility model content
In order to overcome the shortcoming of prior art with not enough, the utility model discloses a kind of rivet welding equalizer bar fixture, comprising base, positioner and expansion mechanism; Described base is hollow box body, and its top is not closed, and four sides are provided with opening; Described positioner is arranged on the side of base; Described expansion mechanism comprises expanding block and push block, and described expanding block is placed on chassis interior and mutually leaves gap, and described push block is arranged on chassis interior and is positioned at by the opening of base two symmetric side.
Further, described positioner comprises positioning die carrier, alignment pin, positioning support and positioning cylinder; Described positioning die carrier is fixed on and push block homonymy; Described positioning support is fixed on the not homonymy of described push block, and described positioning cylinder is fixed on described positioning support, and described alignment pin is fixed on described positioning cylinder.
Further, described expanding structure also comprises swelling cylinder, and described swelling cylinder is connected with described push block and is fixed on positioning die carrier.
Further, described push block is wedge shape.
Further, the head of described alignment pin is equipped with rubber sleeve.
The utility model structure is simple, convenient and practical, the orientation problem of punch assembly during equalizer bar rivet welding can be solved well, and equalizer bar and filler depart from the problem of difficulty after welding, can also save time in addition, reduce productive labor intensity, improve the efficiency of staff and the quality of product.
In order to understand better and implement, describe the utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is front view of the present utility model.
Fig. 3 is side view of the present utility model.
Fig. 4 is top view of the present utility model.

Specific embodiment
Referring to Fig. 1-5, Fig. 1 is schematic diagram of the present utility model, and Fig. 2 is front view of the present utility model, and Fig. 3 is side view of the present utility model, and Fig. 4 is top view of the present utility model, and Fig. 5 is base schematic diagram of the present utility model.A kind of rivet welding equalizer bar fixture, comprises base 1, positioner 2 and expansion mechanism 3; Described base 1 is hollow box body, and its top is not closed, and four sides are provided with opening; Described positioner 2 is arranged on the side of base 1; Described expansion mechanism 3 comprises expanding block 32 and push block 33, and described expanding block 32 is placed on base 1 inside and mutually leaves gap, and described push block 33 is arranged on base 1 inside and is positioned at by the opening of base 1 two symmetric side.In the present embodiment, the assembly of equalizer bar is placed on base 1 successively, and assembly fixes by positioner 2, and the expanding block 32 in expansion mechanism 3 is placed on base 1 inside and its lateral area is more smaller than the opening of base 1, thus can stretch out from this opening when swelling.
Described positioner 2 comprises positioning die carrier 21, positioning support 22 and positioning cylinder 23; Described positioning die carrier 21 is fixed on and push block 33 homonymy; Described positioning support 22 is fixed on the not homonymy of described push block 33, and described positioning cylinder 23 is fixed on described positioning support 22, and described alignment pin 24 is fixed on described positioning cylinder 23.Positioning die carrier 21 is arranged on the symmetrical side of base 1 two can limit the slip of base 1 in this side surface direction.Assembly is pressed on base 1 by the driving of positioning cylinder 23 by alignment pin 24, thus the slip of restriction base 1 in this side surface direction and assembly is fixed on base 1.
Described expanding structure also comprises swelling cylinder 31, and described swelling cylinder 31 is connected with described push block 33 and is fixed on positioning die carrier 21.Swelling cylinder 31 promotes push block 33 and advances toward the gap of expanding block 32, and expanding block 32 is moved toward the outside of base 1.
Described push block 33 is wedge shape.Push block 33 is made more easily to insert gap between expanding block 32.
The head of alignment pin 24 described in the present embodiment is equipped with rubber sleeve, causes damage when alignment pin 24 pairs of punch assemblies can be avoided to position.
Workflow of the present utility model is as follows, the punch assembly of equalizer bar is first placed on base 1 by staff, then drive positioning cylinder 23 to promote alignment pin 24 and hold out against punch assembly, drive swelling cylinder 31 to promote push block 33 again and insert gap between expanding block 32, after expanding block 32 is strutted in punch assembly stretching, and then carry out rivet welding work.After rivet welding, first drive alignment pin 24 to leave equalizer bar, and then drive push block 33 to leave expanding block 32, finally remove equalizer bar again.Due in welding process during equalizer bar expanded by heating by expanding block 32 stretching, so equalizer bar can not cause compressing to base 1, after push block 33 is extracted out from the space of expanding block 32, expanding block 32 can leave equalizer bar easily, thus allows staff can take equalizer bar away quickly and easily.
The utility model structure is simple, convenient and practical, the orientation problem of punch assembly during equalizer bar rivet welding can be solved well, and equalizer bar and filler depart from the problem of difficulty after welding, can also save time in addition, reduce productive labor intensity, improve the efficiency of staff and the quality of product.
The utility model is not limited to above-mentioned embodiment, if do not depart from spirit and scope of the present utility model to various change of the present utility model or distortion, if these are changed and distortion belongs within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these changes and distortion.
